Green Day Bashes Justin Bieber At iHeart Music Festival — Watch

Green Day should have been honored to play at the opening night of the iHeart Music Festival on Sept. 20, but instead, they used their time onstage to bash Justin Bieber! Watch and read on for more details!

“I’m going to play a f—ing new song,” Billie said upon seeing the warning. “F— this sh–. Gimme a f—ing break. One minute left. One minute f—ing left. You’re going to give me one minute.”

After claiming that Green Day has been around since 1988, Billie continued his tirade, making sure everyone knew him and his band shouldn’t be treated like newbies such as Justin Bieber (who wasn’t even at the show).

“I’m not f—ing Justin Bieber, you mother—-ers. You’ve got to be f—ing joking. I got one minute. One minute left. Now I got nothing left.”
